Title: Wavelength Management in Time and Wavelength Division Multiplexed PONs (TWDM-PONs)
Speaker: Weiqiang Sun, associate professor, Shanghai Jiao Tong University
Abstract: Energy efficiency has long been an important design consideration in Passive Optical Networks. Over the years, significant efforts have been seen in reducing the power consumption on the user side equipments, i.e., Optical Network Units. As the capacity of PONs are increasing in terms of the number of wavelength channels and the line-rate, it is equally important to improve the power efficiency on the Optical Line Terminal (OLT) side. In this presentation, I will introduce our ongoing efforts in reducing the cost and power consumption of the OLTs, by introducing dynamic wavelength management and switching. Our results show that under typical ONU online profiles, the proposed dynamic wavelength management schemes can reduce up to 70% power consumption, without bringing in significant loss in ONU availability.
